Solution
The correct option is C Mammals
In mammals, the nasal chambers are called as nasal vestibules. The nasal vestibules are formed by invagination of skin in embryonic stage and hence nasal vestibules have hair and sebaceous glands. In this manner dust particles cannot cross nasal vestibules. The remaining part of nasal chamber is surrounded by three types of bones- nasal, maxilla and ethmoids. At several places in the nasal passage these bones form outgrowths. These outgrowths are called turbinal bones. Due to these outgrowths, the nasal passage is long and spiral. This helps in making the temperature of air equal to body temperature before it reaches the lungs and does not allows unwanted particles like dust to reach lungs.Therefore, the correct answer is option C.
